Description
Technical field
The invention belongs to genetic engineering and technical field of biological fermentation, specifically, can by single recombinant microorganism
The method that sugar fermentation high-performance bio is converted into 1,3- propane diols.
Background technology
1,3-PD is a kind of important industrial chemicals, can be applied to ink, printing and dyeing, coating, profit as organic solvent
The industries such as lubrication prescription, antifreeze, its topmost purposes is the monomer synthesized as polyester and polyurethane, particularly and terephthaldehyde
Acid polymerization generation polytrimethylene terephthalate (PTT).PTT and PET (polyethylene terephthalate), PBT are (poly- to benzene two
Formic acid butanediol ester) compared to more excellent performance, such as more preferable stain resistance, toughness and resilience and ultraviolet-resistent property
Can wait, additionally have the advantages that wear-resisting, water imbibition is low, low electrostatic.Therefore PTT is considered as the upgrading products of PET, with wide
Wealthy market prospects.
At present, the production method of 1,3-PD mainly includes chemical method and bioanalysis.Chemical method is typically with epoxy third
Alkane or propylene are that raw material synthesizes 1,3-PD by complicated catalytic process.The shortcoming of chemical synthesis is many accessory substances,
Poor selectivity, operating condition needs HTHP, and equipment investment is huge, and raw material is non-renewable resources.Therefore, chemical method production 1,
The processing technology routine of ammediol is substantially superseded at present.
Bioanalysis production 1,3-PD mainly includes two technology paths at present：First, it is that raw material is utilized naturally with glycerine
Micro-organisms 1,3-PD；2nd, 1,3-PD is produced using recombinant microorganism by raw material of glucose.It is specific to introduce such as
Under.
One kind is to produce 1,3-PD using natural microbial by raw material of glycerine.There is natural micro- life in nature
Thing, such as Klebsiella pneumoniae (Klebsiella pneumoniae), butyric acid clostruidium (Clostridium
) and C. freundii (Citrobacter freundii) can will be sweet under conditions of anaerobism or micro- oxygen butyricum
Oil is converted into 1,3-PD, and its metabolic pathway mainly includes two-step reaction, the first step：Glycerine is in the presence of glycerol dehydratase
Dehydration generation 3-HPA, second step：3-HPA is reduced into 1,3- the third two under the catalysis of 1,3-PD dehydrogenase
Alcohol.Wherein glycerol dehydratase is made up of 3 subunits, and its encoding gene is dhaBCE (or dhaB123).Glycerol dehydratase is being urged
Can be inactivated automatically, it is necessary to be activated again in the presence of activity factor during changing dehydrating glycerin.Dehydrating glycerin enzyme activition
The encoding gene of the factor is dhaG and dhaH.Also there is 1,2-PD dehydratase and its activity factor in nature simultaneously can be with
The dehydration of catalyzing glycerol or 1,2-PD, its encoding gene is pduCDEGH.1,3-PD dehydrogenase is a NADH
The alcohol dehydrogenase of dependence, its encoding gene is dhaT.YqhD gene codes in some other alcohol dehydrogenase such as Escherichia coli
The alcohol dehydrogenase that NADPH is relied on can also be catalyzed 3-HPA also original production 1,3-PD.Glycerine is in reduction generation 1,3-
The process of propane diols is, it is necessary to consume reducing power NADH or NADPH, these reducing powers are to be oxidized to other accessory substances by glycerine
Such as acetic acid, lactic acid, the generation such as 2,3-butanediol.
At present, the industrial technique using glycerol production 1,3-PD is mainly using Klebsiella pneumoniae (as in
State patent CN 200810105722.8).The major defect of this process route is：First, Klebsiella pneumoniae is condition cause
Germ, biological safety needs strict control in its production process；2nd, a large amount of accessory substances such as acetic acid, lactic acid, succinic acid, 2,3-
The synthesis of butanediol so that extraction process becomes sufficiently complex after whole；3rd, the yield of 1,3-PD is low, usual 1,3- third
Glycol is less than 40% to the quality yield of glycerine.
There is a kind of side for being to be produced using recombination bacillus coli as raw material with glucose 1,3-PD in the prior art
Method.Nature in the absence of can directly transforming glucose generation 1,3-PD microorganism.E.I.Du Pont Company is by large intestine bar
Glycerine route of synthesis (glyceraldehyde-3 phosphate dehydrogenase and glyceraldehyde-3 phosphate enzyme) of the heterogenous expression from saccharomyces cerevisiae and come from bacterium
The glycerol dehydratase and its activity factor of Klebsiella pneumoniae and the alcohol dehydrogenase of the NADPH dependences using Escherichia coli itself
Enzyme YqhD, realizes step conversion (CN 200380104657.2) from glucose to 1,3-PD.This process route
Have the disadvantage that Escherichia coli are poor biological safeties, the fermented and cultured of Escherichia coli needs to use the raw material dusty yeast of costliness, because
This technology is unfavorable for that industrialized scale metaplasia is produced.
The content of the invention

Ketone, the latter further synthesizes into glycerine under the catalysis of glycerol dehydrogenase.Effect of the glycerine in glycerol dehydratase and alcohol dehydrogenase
Under ultimately generate 1,3- propane diols.The approach is different from the 1,3-PD synthetic method that E.I.Du Pont Company uses, and the main distinction is
E.I.Du Pont Company is by expressing glyceraldehyde-3 phosphate dehydrogenase and glyceraldehyde-3 phosphate lipase come synthetic mesophase glycerol production, and the present invention is carried
